- starch or a polysaccharide derived from starch has long been used as a raw material, and a typical example is oprate.
- oblate was limited because of its poor moisture retention and moisture resistance, very low strength, brittleness, and poor transparency.
- amylose films which are obtained by separating a mouth piece or treating starch with a debranching enzyme to decompose it into amylose, or using a high amylose-rich high amylose starch as it is. This film has some strength, is flexible, does not transmit oxygen, and is oil-resistant.
- amylose film has low moisture retention and moisture resistance, is easily affected by the humidity of the outside air, causes adhesiveness by absorbing moisture, and the aging of amylose during storage, and the drying It has some drawbacks such as weakness and has not been put to practical use.
- capsules can be manufactured using pullulan, but the ones that have been used so far are mainly made of gelatin.
- animal-derived components such as gelatin due to concerns about contamination from livestock infectious diseases such as mad cow disease and foot-and-mouth disease.
- Provision of capsules is required.
- the pullulan-rich molded product had the above-mentioned very useful features, it had a serious drawback that it was susceptible to changes in humidity. That is, in a low-humidity environment, moisture is easily released from the molded product, and the elasticity is reduced accordingly.
- glycerin, sugar alcohol, and the like have been used as plasticizers to solve this problem.However, in a high-humidity environment, the molded product tends to absorb moisture and generally causes an adhesion phenomenon. There was an inconvenience.
- the present invention is based on the fact that molded products with a high pullulan content, which are produced using conventional manufacturing techniques, have low stability against changes in humidity, and are useful for handling molded products and for manufacturing secondary processed products that use molded products as raw materials. Eliminate disadvantages such as the necessity of strict humidity control and other difficulties in handling products, and establish films with high pullulan content, such as films, sheets, and capsules, that are highly stable against humidity changes.

Even if it is performed, no particularly remarkable effect is obtained in terms of moisture retention and moisture resistance.
- Examples of the molded product having a high pullulan content include a molded product obtained by molding an aqueous solution containing pullulan by a casting method, or a molded product using a predetermined mold, for example, a film, a sheet, or a force cell. Further, if necessary, an amorphous solid which may be prepared by crushing a molded product once formed may be used as a method for producing a pullulan film which is one of the molded products having a high pullulan content. As described in JP-A-54-135655, a pullulan aqueous solution is cast on a heated rotary drum or an endless belt, and the water content of the aqueous solution evaporates, resulting in a water content of 4 to 13.

The range is preferably from 50% to 50%. If the concentration of pullulan is low, it will flow over the synthetic plastic film used as a substrate during molding, and it will take time to heat and dry, and a lot of energy will be required. If the concentration is too high, if the pullulan used is a powder, it takes time to dissolve, and even if the temperature of the aqueous solution is high, the viscosity is high and the operability during molding is poor.
- the liquid temperature is usually in the range of 15 to 95 ° C, preferably in the range of 50 to 80 ° C. . If the liquid temperature at the time of preparing the aqueous pullulan solution is low, it takes time to dissolve the pullulan, and if the liquid temperature at the time of using the aqueous pullulan solution for molding is low, the viscosity becomes high and the drying efficiency becomes poor. Conversely, if the liquid temperature is too high, not only is there danger at the time of work, but when additives are added to the aqueous pullulan solution, depending on the additives, denaturation may occur or evaporation and scattering may occur.
- the content of ⁇ , 1-trehalose is preferably in the range of 0.1 to 90%, more preferably in the range of 0.5 to 60%, in terms of anhydride, based on the main raw material pullulan. It is. If the content is too small, the effect of imparting stability to humidity change cannot be expected, and if it is too large, molding as a molded article becomes difficult, or the molded article obtained is very brittle even though molding is possible And its handling becomes difficult.
- a known plasticizer such as glycerin or sugar alcohol may be optionally used in combination. When the molded product is a film, heat sealing becomes easy and the production of a bag-like material becomes easy by using these plasticizers in combination.
- a surfactant such as various fatty acid esters having an emulsifying action is used as a release agent.
- the amount of sucrose fatty acid ester added as a release agent during the preparation of the pullulan film is usually in the range of 10% or less, preferably in the range of 0.05% to 5% with respect to the main raw material pullulan. It is suitable. If the amount is too small, depending on the composition of the pullulan film, the releasability from a holding substrate such as a synthetic plastic film or a metal plate will deteriorate. Loss of properties and peeling during drying, making drying difficult.
- the pullulan content in the molded product is determined by extracting the molded product using water or hot water, decomposing the pullulan contained in the extract using pullulanase, and measuring the amount of maltotriose produced.
- Required cosmetics and pharmaceutical applications include packs, oral preparations, haptics, solidified bases for various drugs, bases for drug administration for transdermal and transmucosal absorption, sustained release bases, packaging materials, etc. There is.
- the manufactured product having a high pullulan content has excellent stability against a change in humidity.
